Embodiment 1

[0041] Embodiment 1, preparation functional sewing non-woven fabric

[0042] (1) take by weighing the nylon fiber of 50 mass parts, the hemp fiber of 30 mass parts and the polypropylene fiber of 20 mass parts as the compound material of preparing hydrophobic layer I;

[0043] Take by weighing the nylon fiber of 40 mass parts, the hemp fiber of 40 mass parts and the polypropylene fiber of 15 mass parts as the compound material of preparing hydrophilic layer;

[0044] Weigh 50 parts by mass of nylon fiber, 30 parts by mass of hemp fiber and 20 parts by mass of polypropylene fiber as a mixture for preparing the hydrophobic layer II.

[0045] The fibers weighed above are opened and carded to obtain a lap, and the lap is needled and combed to obtain a hydrophobic fiber web I, a hydrophilic fiber web and a hydrophobic fiber web II. Lay the above-mentioned hydrophobic fiber net I, hydrophilic fiber net and hydrophobic fiber net II, and obtain a non-woven fabric in which the hydropho...

Embodiment 2

[0068] Embodiment 2, preparation vamp composite cloth

[0069] Blend polyester staple fiber, hemp fiber and cotton fiber to obtain single yarn, wherein the mass ratio of polyester staple fiber, hemp fiber and cotton fiber is 50:25:25; The yarn is plied to obtain ply yarn, and then woven fabric is obtained through weaving, which is the shoe fabric, wherein the mass ratio of blended staple fiber to polyester long yarn is 45:55. The gram weight of the obtained shoe fabric is 420 grams / m 2 , a width of 150 cm.

[0070] The above-mentioned obtained shoe material and the seam-bonded non-woven fabric prepared in Example 1 (the grammage is 250 grams / m 2 ) use PUR hot-melt adhesive for paste dot compounding, in which the end face with the largest hemp content in the shoe lining is compounded with the shoe fabric, the controlled compounding temperature is 120°C, the pressure is 4.0ba, and the amount of glue is 20g / m 2 .

[0071] Some physical and chemical parameters of the shoe uppe...

Abstract

The invention discloses a composite vamp fabric with gradient functions and a preparation method thereof. The composite vamp fabric is composed of a surface fabric and a lining which are superposed successively; the surface fabric is a blended fabric prepared by blending fibers including polyester fibers, China hemp fibers and cotton fibers; the lining is a stitch-bonded non-woven fabric comprising a hydrophobic layer I, a hydrophilic layer and a hydrophobic layer II which are superposed successively; and the hydrophobic layer I, the hydrophilic layer and the hydrophobic layer II are all composed of hydrophobic fibers, hydrophilic fibers and hot-melt bonding fibers. The gradient functions refer to that the air permeability, wet permeability, quick-drying performance, strength and wear resistance of the composite vamp fabric increase from lining layer to surface layer of the composite vamp fabric while the hygroscopicity and antibacterial property of the composite vamp fabric decrease. The composite vamp fabric provided by the invention has good hygroscopicity and quick-drying performance, is antibacterial and deodorant, and is comfortable to wear; and the strength of the composite vamp fabric meets needs of wearing, so shoe making cost can be reduced, and shoe quality is improved.

Description

technical field [0001] The invention relates to a composite shoe upper cloth with gradient function and a preparation method thereof. Background technique [0002] At present, the upper composite fabric of sports shoes is mainly polyester filaments. Polyester fibers have high strength, good elasticity, and good wear resistance, but poor water absorption. Cotton sports shoe cloth has disadvantages such as insufficient wearing fastness, poor abrasion resistance, and not easy to dry after washing, but it has excellent moisture absorption performance. Although hemp fiber has antibacterial and quick-drying properties, its strength and abrasion resistance need to be strengthened. [0003] The antibacterial function of fabrics is mainly achieved by two methods: fiber modification and fabric finishing. Antibacterial finishing agents can be divided into two categories: dissolution type and non-dissolution type. The dissolution-type antibacterial agent needs to be fixed on the fibe...
